Description of the project context:

Automotive mobility will undergo a profound change in the coming years: electrification and environmental constraints, driving automation, a shared and connected mobility will transform passenger habits and expectations. The vehicle is no longer just a means of transport but becomes a living space in its own right, open to socialization, work and leisure.

In this context, the benefits of comfort and well-being on board will become differentiating factors more and more appreciated by the manufacturers.

The management of thermal comfort, as well as related psycho-physiological conditions such as stress or tiredness, is a major component of comfort in vehicles. Especially since it is the second consumer of energy after driving. On the so-called “premium” vehicles and more broadly in the form of options, it is necessary to be able to offer a comfort that is both individualized and personalized, with a double challenge: to reduce its impact on consumption and to adapt it to every context of use.


The objectives of the innovation project:

The project aims to develop a new approach to passenger comfort in summer by using a network of “smart” aerators at different points in the passenger compartment. Thanks to a greater proximity of the passengers, these aerators will be able to generate localized thermal sensations with a lower energetic cost. They must also adapt more easily to a change in the position or posture of passengers, particularly in the phases of delegated or autonomous driving.

The original characteristics of these aerators will have to satisfy three specific functions:

  • High compactness for easy integration into various areas of the passenger compartment, such as pillars or skylights, as well as strong attention to the exterior, especially to ensure durability and avoid embarrassment for passengers.
  • A motorized ventilation nozzle combined with a specific aeraulic design to control the shape of the air jet, between a highly directional “spot” mode and a very open “diffuse” mode. These different modes and the transitions between modes will have to be optimized to minimize the pressure loss and the associated airflow noise.
  • A motorized ventilation head to orient the direction of the air jet, in site around a horizontal axis to fit different sizes or area of ​​the body, and in azimuth around a vertical axis to fit different configurations of the cabin. The silence of the actuators will be a sensitive point here.



  • The stakes and constraints of the project address, as a priority, certain technological bricks or specific expertise:
  • Ultra-compact, silent, precise and responsive actuators and kinematics for motorizing the orientation of aerators and modulating the shape of the air jet
  • Aeraulic design of the ventilation nozzle, relying partly on CFD simulations, with movable elements making it possible to vary the shape of the jet (directional / diffuse) while minimizing the pressure loss and associated airflow noise
  • Use of materials and methods of realization allowing the implementation of components with dimensions and reduced dimensional tolerances, and surface conditions peculiar to the parts of aspect
  • In all cases, the proposed solutions must be compatible with automobile constraints, both in terms of use and environment (temperature, humidity, vibrations, cycles, service life …), and the possibility of production at a reduced cost and high volumes (> 1 Mp / y).
